Question

Find the remainder when p(x) = 12x3 – 13x2 – 5x + 7 is divided by 3x +2, using remainder theorem.

Answer 1

Step-by-step explanation:

let 3x + 2 = 0 => 3x = -2 => x = -2/3

So,

p(-2/3) = 12(-2/3) ^3 - 13(-2/3) ^2 - 5(-2/3) + 7

= -32/9 - 52/9 + 30/9 + 63/9

= (93-84) /9 = 9/9 = 1

Hope you get it. Best of luck buddy.
